Computer thowing low and high vlotage codes for the O2 sensor. Left bank is the passenger side right?

 

No it's right side. I guess if you were outside the USA it would be the left side..haha. Don't mistake left and right with Bank 1 and Bank 2. They don't necessarily match each other odd/even. The DTC should read either bank 1 or bank 2...which is it? And which engine? Bank 1 will be the bank that cylinder number 1 is. Number one is always the cylinder head that sits forward.

Clear as mudd?? lol
